Laizhou, Shandong: Bagging Apple Picking Technology
1. During the bag removal period, watering is performed 2-3 days before bag extraction. Yellow-green varieties of single-layer bags can be removed at the time of harvest; red varieties use single-layer bags, about 30 days before harvest; red varieties use double bags, 20-25 days before fruit harvest. The best time to remove the bag from 9:00 to 11:00 and from 15:00 to 17:00 in the morning, except for the paper bag on the south side, must avoid the strongest time of daylight at noon, so as not to cause the fruit to suffer sunburn.
2. Bag removal method The single-layer bag tears the bag body into an umbrella shape, covers the fruit and prevents direct sunlight on the fruit surface, and removes the whole bag after 7-10 days to prevent sunburn and accelerate coloration; the red variety uses inner and outer layers. To separate the double bags, take the outer bag 20-25 days before the harvest, remove the inner bag after 4-5 sunny days, double the outer bag and the inner bag, and then release the bag first. Ventilation of the mouth, remove it after 4-5 days.
3. Management after picking the bag (1) Picking leaves, transferring fruits, and placing fruits. For the first time around the first half of the bag collection, the leaves attached to the bagged fruit and within 5 cm of the surrounding area were removed. The second time, about 5 days after the bag was removed, the senescent leaves, yellow leaves, leaflets, and thin leaves of the base were removed. Pick the middle and upper effective leaves, and when the leaves are picked, use scissors to cut off the leaves (retain the petiole). The amount of leaf picked can be controlled at 15-20%.
After the fruit-turning period, after changing the color on the sun surface, change the position of the shoots and the direction of the fruit to turn the dark side of the fruit to the sunny side. The fruit-transfer time is to be performed before 10 o'clock in the morning and after 4 o'clock in the afternoon to prevent sunburn. The padding is made by using a paper bag that has been removed or a special plastic mat that is produced in factory.
(2) Reflective plastic film. After removing the leaves from the bag, the silver-gray reflective plastic film was placed under the tree to promote fruit coloring.
